3. 3 Harmonization actions (1) 3GPP – 3GPP2 Joint meetings since 1999 addressing interoperability, roaming and harmonization needs, centred on:Joint meetings since 1999 addressing interoperability, roaming and harmonization needs, centred on: –Radio access –Terminal design –Core network Results:Results: –Joint studies on radio matters such as spacial Channel modelling, common User Equipment requirements, etc –IMS adopted by 3GPP2 –Potential barriers to interworking and roaming between 3GPP and 3GPP2 systems being resolved in Release 6 Microsoft

4. 4 Harmonization actions (2) 3GPP – ITU ITU - RITU - R –Regular updates submitted to ITU-R Recommendation M.1457 High level description of IMT-2000 air interfacesHigh level description of IMT-2000 air interfaces ITU - TITU - T –Collaboration with ITU-T Special Study Group on "IMT-2000 and beyond" –Regular updates submitted to ITU-R Recommendation Q.1701 Framework for IMT-2000 networksFramework for IMT-2000 networks

5. 5 Harmonization actions (3) 3GPP – IETF Harmonization also being enhanced by adoption of external common specificationsHarmonization also being enhanced by adoption of external common specifications –Notably, IETF RFCs (approx. 40) –RFC 3113 defines basis of co-operation between 3GPP & IETF –IMS based on SIP, defined by IETF… SIP in original form not adequate for 3GPPSIP in original form not adequate for 3GPP –signalling, voice and radio efficiency issues But 3GPP did not want a 3GPP specific version of SIPBut 3GPP did not want a 3GPP specific version of SIP –would prevent interworking 3GPP-IETF collaboration has provided required SIP extensions and IETF interoperability changes3GPP-IETF collaboration has provided required SIP extensions and IETF interoperability changes Collaboration continues…Collaboration continues…
